Patent NL-256314-A (NL)
IPC: C08B30/16
Abstract: <PICT:0916482/III/1> In a continuous method for contacting finely divided particles, e.g. starch, with a gas, e.g. anhydrous hydrogen chloride, a stream of the particles is conveyed through a confined contact space containing the gas and having an inlet and outlet arranged so that they are continuously filled with the particles to prevent escape of the gas.  Particles are fed from a belt 41 (Fig. 1) to a conveyer 10 having a floor 11 and sides 12, which is mounted on a carrier 13 vibrated by an eccentric 19, carrier 13 being supported on flexible struts 28.  The vibrations cause the particles M to flow from right to left, passing through a chamber 32 filled with gas supplied by diffuser 39.  The conveyer floor 11 has V-shaped transverse depressions 35 and 351 below end walls 34 and 341 forming an inlet 36 and an outlet 37.  The particles flow down into and up out of depressions 35 and 351 filling inlet 36 and outlet 37.  Dust formation at openings 36 and 37 is eliminated by flanges 38 and 381. The floor 11 has transverse protuberances 27 which mix the stream of particles to ensure uniform contact with the gas.  Carrier 13 is in the form of a channel and conducts material discharged from conveyer 10.ALSO:In a continuous method for contacting finely divided particles of starch with anhydrous hydrogen chloride, a stream of the particles is conveyed through a confined contact space containing the gas and having an inlet and outlet <PICT:0916482/IV(a)/1> arranged so that they are continuously filled with the particles to prevent escape of the gas.

Title: Curved sheaths, for sausage casings, made from synthetic pipes - wound on heated arbors and heated locally to set
IPC: B29C35/04
Filed: 1976-02-12
Abstract: Curved sleeves cut from a spirally coiled pipe of synthetic material to be used as casings for sausages, are produced by filling the tube with a gas, such as air, sealing both ends, and winding the tube on to a rotating, heated arbor. As the spirals are formed, they are heated locally on their outer surfaces. The tube is held under some tension whilst it is being wound on to the smooth rotating arbor. A much longer length of tube can be wound into a coil at high speed, whilst ensuring greater uniformity in the product. The expansion of the air inside stretches the outside of the sleeve and presses the inside against the arbor. Too great a shrinkage and thickening is prevented by the initial tension whilst the sleeve is being wound.

Abstract: A clock generator for a pulse repeater of a receiver in a pulse transmission system comprises a forward filter (1) connected to its input (A), a difference former (2) whose positive input is connected to the output of the forward filter (1), a series arrangement connected between the output of the difference former (2) and the output (B) of the clock pulse generator and comprising a limiter (3), a time differentiator (4), a rectifier (5) and a narrow bandpass filter (10) in this order, and a feedback filter (6) connected between the output of the limiter (3) or the rectifier (5) and the negative input of the difference former (2). The limiter (3) is used to cancel intersymbol interference. The clock generator can be utilized in combination with a known pulse signal regenerator (1,7-9) of the decision feedback type to constitute a pulse repeater. Alternatively, a pulse repeater can be obtained by combining the clock generator with only a pulse regenerator (8, Fig. 2) whose clock input is connected to the output (B) of the clock generator, whose signal input is connected to the output of the rectifier(5) of the clock generator and whose output constitutes the output (c) of the pulse repeater. When using a known pulse signal regenerator of the decision feedback type, the forward filter can be common to the pulse signal regenerator and the clock generator and the respective feedback filters can have the same amplitude-frequency characteristic.

Title: Inspection instrument for human or animal sphincter muscles - uses resistance to water flow as measure of sphincter wall strength
IPC: A61B5/22
Filed: 1987-04-29
Abstract: Distilled water at a pressure of 200 kPa is fed from a reservoir (12) via flow constrictions (11) and pressure transducers (10) to eight supply pipes (9). From the supply pipes flexible hoses take the water to a catheter (7). The catheter is inserted into the sphincter and the water is ejected from eight radial holes (8) near the tip of the catheter. The catheter is slowly withdrawn from the sphincter and the resistance to the flow from each hole is recorded. The outputs of the pressure transducers (10) are amplified (13) and converted (14) to digital form. The digital signals are held in a buffer memory (1) and processed by a CPU (2) which has a keyboard (3), VDU (4), printer (5) and floppy disc drive (6). The resultant VDU image is a cross-section of the sphincter which shows weaknesses, restrictions, obstructions etc..

Title: Machine to automatically bond concrete bricks and sand- lime bricks in the construction industry
IPC: E04G21/22
Filed: 1992-07-21
Abstract: The invention relates to a machine to automatically bond concrete bricks and sand-lime bricks in the construction industry, bricks of the Maas-Waal-Amstel format. The machine is able to deliver the bricks automatically on roller conveyors, to provide the bricks with a film of adhesive by means of adhesive spreading rollers, and to position them in the correct position by means of a gripper, ultimately resulting in a complete wall. Openings in the wall for the purpose of doors or windows can be programmed by simple control procedures. The machine then automatically leaves those openings free from brick and adhesive. A machine operator, who may be standing on a platform, supervises the activities and occasionally puts half bricks in position to ensure that the rows of the wall are staggered. <IMAGE>
